Seven children (aged 8--17 years) presented with a high fever, headache, confusion, conjunctival hyperaemia, a scarlatiniform rash, subcutaneous oedema, vomiting, watery diarrhoea, oliguria, and a propensity to acute renal failure, hepatic abnormalities, disseminated intravascular coagulation, and severe prolonged shock. One patient died, one had gangrene of the toes, and all have had fine desquamation of affected skin and peeling of palms and soles during convalescence. Five patients were studied prospectively. Staphylococcus aureus related to phage-group I was isolated from mucosal (nasopharyngeal, vaginal, tracheal), or sequestered (empyema, abscess) sites, but not from blood. This organism produces an exotoxin which causes a positive Nikolsky sign in the newborn mouse and which is biochemically, pathologically, and immunologically distinct from phage-group-II stapphylococcal exfoliatin.

Streptozotocin (STZ) has shown antitumor activity against various tumors in man, but the clinical usefulness of this drug has been limited, mainly because of renal and gastrointestinal toxicity. Nineteen patients with advanced cancer of various types were given a mean dose of 3.4 g/m2 of STZ by continuous iv infusion over 5-6 days each month for one or two monthly cycles. Basic serum and urine studies were performed immediately before and after each treatment cycle. Following STZ treatment, no significant changes in BUN or creatinine were seen. Four patients in whom initial tests for proteinuria were negative developed grade 1 or 2+ proteinuria after completion of the treatment cycle. No myelosuppression or renal failure was observed. Six patients had no nausea or vomiting, seven patients had nausea only, three patients had nausea and vomiting which were well-controlled with antiemetics, and three patients had uncontrollable nausea and vomiting. Confusion, lethargy, and depression were noted in five patients who had no prior central nervous system abnormalities; these effects appeared during treatment or in the immediate posttreatment period. Two patients with diffuse non-Hodgkin's lymphoma had complete remission, while several other patients had documented improvement. Although central nervous system toxicity may be a limiting factor, prolonged STZ infusions may have significant clinical promise.

A 3-yr-old boy was investigated for numerous episodes of fatigue, irritability, pallor, and sweating, which began at 11 mo of age, when he had an episode of symptomatic hypoglycemia with ketonuria. He had euphoria, mental confusion, drowsiness, nausea, and vomiting 1-5 hr after oral administration of glycerol in doses of 0.5-1.0gm/kg. Orally administered MCT (1 gm/kg) had similar effects. On one occasion, oral glycerol also provoked hypoglycemia, as had a 16 1/2 hr fast. Intravenously administered glycerol (0.09 gm/kg) induced an immediate loss of consciousness from which he recovered spontaneously after 30 min; there were no changes in blood glucose values. Intravenously administered fructose (0.25 gm/kg) was tolerated normally. Leukocytes showed normal activities for FDPase, glycerol kinase, and glycerol phosphate dehydrogenase. The restriction of dietary intake of fat has been associated with a marked improvement in physical and mental activities. These observations suggest a unique, yet undifined intolerance to glycerol, which suggest caution in the diagnostic use of glycerol in the investigation of hypoglycemia as well as in the therapy of increased intracranial or intraocular pressure.

The effect of guancydine (1-cyano-3-tert-amylguanidine) on systemic and renal hemodynamics was studied in nine patients with arterial hypertension. Antihypertensive drugs were withheld for 15 days before beginning the investigation. Average sodium intake was 105 meq/24 hours in some patients and 25 meq/24 hours in others. Patients received placebo during a control period that averaged 14 days. Guancydine was given for 7 to 18 days at an average dose of 21 mg/kg of body weight. Although mean arterial blood pressure decreased significantly in all patients, it reached normal levels in only two. There was no change in cardiac output. Glomerular filtration rate and renal plasma flow remained unchanged, whereas urinary sodium excretion diminished, suggesting an activation of the renin-angiotensin-aldosterone system. A substantial gain in body weight was noted. Nausea, vomiting, constipation, somnolence, restlessness, mental confusion, asthenia, and urine retention were observed. The anti-angiotensin effect of guancydine that has been described in animals was not observed.

A 45-year-old man ate about 10 gm of dapsone (DDS). After initial vomiting marked methemoglobinemia with cyanosis, headache, and confusion developed. Methemoglobinemia subsided 7 days after ingestion when the concentrations of DDS and monoacetyldapsone (MADDS) were at the therapeutic level. Signs of hemolysis appeared on the third day after DDS ingestion, the hemolysis being maximal more than one week after ingestion. The initial disappearance of DDS and MADDS was slow, the apparent half-lives being 88 and 67 hr, respectively. Peroral activated charcoal seemed to shorten the half-lives of DDS and MADDS markedly. This result supports the concept of the enterohepatic cycle of dapsone and recommends the use of activated charcoal for several days in acute poisonings caused by DDS.

Case histories of four elderly patients with central nervous system signs of digitalis toxicity were reviewed. Evidence of toxicity included lethargy, depression which was not present previously, confusion, restlessness, emotional instability, hyperventilation, and vertigo. Vomiting developed four days after the onset of the mental changes. No cardiac arrhythmias were observed. Digoxin serum levels ranged between 4.2 and 7.0 ng/ml. Serum potassium values were within normal limits. Three of the four patients recovered with a return of their mental status to the pretoxic state. The fourth case was fatal. At autopsy long-standing myocardial ischemia was the only significant finding.

Histoplasma meningitis (HM) has been reported to occur primarily in association with disseminated histoplasmosis (DH). We report a case of histoplasma meningitis occurring in a patient with common variable hypogammaglobulinemia (CVH) in which no manifestations of DH were observed. L. L., a 66-year-old Caucasian male, clerical worker, developed occasional episodes of dizziness and tinnitus in mid-1971. During 1972, increasing frequency of these episodes and gradually progressive confusion were noted. In January 1973, vomiting, forther confusion, obnubilation, and a left central facial paresis developed and he was hospitalized. Physical examination revealed no pulmonary abnormalities, lymphadenopathy or hepatosplenomegaly. Over the ensuing 6-week evaluation, there was occasional fever to 38.5 degrees C. Chest roentgenogram was normal. Cerebral angiography suggested a mass in the left cerebellar hemisphere. EEG was diffusely slow. Multiple CSF examinations revealed: Glucose 7-18 mg/with a normal blood glucose, protein 109-256 mg/and cells 66-140 (95 + % mononuclear). Histoplasma capsulatum was cultured from CSF but not from sputum, urine, blood or bone marrow. Skin tests for PPD, histoplasmosis, coccidiodomycosis, blastomycosis, mumps, dinitrochlorobenzene and streptokinase-streptodornase were negative then and 6 months later. Histoplasma serum antibody was absent. Immunoglobulin analysis revealed IgG 430 mg %, IgA 46 mg %, and IgM 35 mg %, which with the history and skin test results suggested CVH. Treatment with 2.51 gm of amphotericin B given intravenously over a 3-month period resulted in complete reversal of all neurologic signs and clearing of the confusion. The remission has been maintained for two years. This case represents a primary infection of the CNS by histoplasma. The relationship between the HM and the CVH will be discussed.

A case of chlorpropamide-induced, symptomatic hyponatremia in a diabetic patient is reported. The hyponatremia was associated with loss of appetite, nausea, and vomiting. These symptoms caused reduced food intake which provoked severe hypoglycemia with disturbed consciousness. The hyponatremia developed when the chlorpropamide doses were increased from 400 to 600 mg/day. Withdrawal of chlorpropamide was followed by remission of hyponatremia. Chlorpropamide-induced hyponatremia is a rare complication and is due to an antidiuretic effect of chlorpropamide caused by increased secretion of adiuretin and potentiation of the effect of chlorpropamide caused by increased secretion of adiuretin and potentiation of the effect of adiuretin in the tubuli of the kidney. This case report and the analysis of 18 published cases in the literature show the following characteristics for chlorpropamide-induced hyponatremia: (1) Hyponatremia is a rare complication in the treatment of diabetics with chlorpropamide. The patients typically are female and over sixty. The dosage of chlorpropamide usually was 500 mg daily or even more. (2) Hyponatremia is often unrecognized for a long time because the symptoms are not specific. The characteristic symptoms include loss of appetite, nausea, vomiting, abdominal pain, confusional state and, rarely, convulsions and coma. Recovery occurs spontaneously after withdrawal of the drug. (3) The incidence of this type of hyponatremia is increased in cases of preexisting tendency to water retention such as heart failure and renal failure, and in cases of diuretic therapy. In the light of these findings, the authors believe that chlorpropamide is no longer a drug of choice in the treatment of diabetic women, especially in cases of preexisting tendency to water retention and in diuretic therapy. In such cases, a sulfonylurea without antidiuretic effect is to be preferred.

Thirty-three patients with metastatic brain neoplasms of various types received glycerol instead of corticosteroids during periods of brain irradiation. In the 25 symptomatic patients, responses from this treatment were seen in those patients whose primary symptom was vomiting (ten of 12 patients), headache (nine of ten), papilledema (five of nine), paralysis (six of eight), confusion (six of seven), and dysphasia (four of six). Glycerol was well tolerated; it did not induce immunosuppression when administered in combination with radiotherapy and chemoimmunotherapy. Further investigation is indicated to compare its efficacy with that of dexamethasone.

Three patients ate different amounts of a common northern mushroom, brown fly agaric, Amanita regalis. All of them believed they had eaten delicious parasol mushrooms, Macrolepiota procera. The symptoms of poisoning began 1--2 hours after ingestion of the mushrooms. All the patients had marked gastrointestinal symptoms: nausea and heavy vomiting. Two had central nervous system manifestations and cholinergic symptoms: hallucinations, confusion, or loss of consciousness as well as copious salivation, or sweating. All patients recovered within 4--24 hours without any damage to liver, kidneys or central nervous system. It seems that cooking the mushrooms does not completely neutralize the toxic agents of Amanita regalis. The analysis of fried mushrooms shows that it may be possible to identify mushrooms reliably from the remains of a meal.
